A sound wave completes one oscillation in 0.002 s and moves a distance of 30 cm. Find the velocity of the wave.

Text Solution

Verified by Experts

Given: T= 0.002 s, wavelength (`lamda`)= 30 cm=`30/100`m=0.3m
Now, frequency (f) =`1/T=1/(0.002s)=2000Hz`
`therefore v=flamda=2000Hzxx0.3m=600ms^(-1)`
